YSCRIIIIBIBING BRUSH.

Application filed April 2, 1927.. Serial No. 180,578.

cause it the soap is placed in the water While in disuse, a considerableportion of it dissolves and if it is laid upon the floor, while indisuse, valuable time and effort of the user is consumed in reaching orwalking to get it when it is desired to apply it to the brush.

Furthermore, the users of the ordinary screbbing-brushes, when scrubbinga floor, have found it necessary to stoop to the knees "for the purposeof applying the brush in frictional contact with the floor, whichposition is extremely tiresome as Well as result ing in the garmentscovering the knees of the person using the brush becoming soiled,.andoften saturated with unclean water.

Therefore, the objects ofthe invention are to provide a simple,efiicient and durable scrubbing-brush adapted to contain soap; to.provide simple manually operative means to cause the soap to be quicklyand'conveniently applied to the bristles of the brush in quantitiessuitedto the requirement of the particular work being accomplished, andin accordance with the desires of'the user; to provide means wherebythe'user of said brush may'utilize it in scrubbing floors, Walls and thelike, while standing inan erect position; to provide means wherebythesoap is adapted to be applied directly tothe bristles of thebrush; andto provide means whereby the bristles or the brush and the retainerthereof may be quickly and. conveniently substituted for fresh and newones whenthe old bristles are worn and require replacement.

The invention consists in the combination of the elements, arrangementof the parts, and in the details of the construction, as

In the preferred construction of the: in

vention,.I provide scrubbing-brush 1 of lower side 7 tl1ereofl In Figs.3 and 4 is shown a V-shape soap I distributor plate 8 (formed fromresilient metal) haying. grooves 9, in its top 9. i The grooves e rtendfrom shed 10 to holes 11 havingzthe upper ends 12 of tubes 13 securedtapered outwardly from the shed.

. The distributorgplate 8 is adapted toxfit in opening 3, of easing 2,with the, tubes 13 pro ect ng downwardly into holes 15 in bristleretainer 4 in the manner 'shownin Fig.2.w

Within therasing 2 is plate lfilhaving outer edges 17 secured, as bysolder, to the inner sides of'sideswalls lii and end-walls 1.9 of thecasing, whereby liquid, soap compartment 20 is-provided-in the casing.The plate 16 is spaeeda suflicient distance from the bottom edge'21of'the casing, iii-consideration of the other parts of the invention topermit the edge 21 to be in alignment with the lower side 7 of theretainer4, as shown in Fig. 2, when the parts of the scrubbingbrush areassembled.

Secured in holes 22 and 23, respectively, in plate 16 and top 24, of thecasing, is tubular cylinder 25, having perforations 26 in its lower end27. Slidably received in hole 28 of the tubular cylinder is 'pushrod 29having its upper end 30 protruding from casing 2. The stopper 14, fixedto distributor 8, is normally received in the lower end of cylinder toprevent the liquid soap 31 from draining through perforations 26, fromcompartment 20 onto the distributor.

When downward force is exerted on top 30, ofrod 29, the lower end 32, ofthe rod, is adapted to engage top 33 of stopper 14 (as shown in Fig. 11)whereby the liquid soap 31 contained in compartment 20, of the casing,is adapted to drain through perforations 26, in the lower end 27 ofcylinder 25, and thence through the lower end of the cylinder, uponstopper 14 and shed 10, of the distributor, whereby the flow of theliquid soap is divided and conveyed by the grooves 9, through grooves 13into tubes 13, from whence it flows in contact with bristles 6 of thebrush 5.

1 When a sufficient quantity of soap has flowed from compartment 20 uponthe bristles 6, of the brush 5, downward pressure against top of thepush-rod 29 is released, and the compression and tension of theresilient metal in distributor 8 is adapted to force the stopper 14 inhole 28 of the cylinder 25, thereby blocking turtherflow of the liquidsoap from compartmentv 20 of the casing until the pushrod againismanually forced downwardly.

In Fig. 9 is shown handle 35 having arms 36 suitably secured to'itslower end 37. The ends 38 of the arms may be manually spread from eachother tobe rotatably received in holes 39 in the ends of the casing.Received through the hole 40, and extending longitudinally of thehandle, is stafl 41 having its upper end 42 protruding from the outerend 43 of the handle, whereby the scrubbingbrush 1 may be moved infrictional contact with the floor, wall, or the like, as by manuallyoperating the handle. When the user desires to apply soap in contactwith the bristles 6, the operator simply presses the upper end'42ofstaff 41 downwardly, whereby the lower, end 37 of the staff operativelyengages the top 30 of push-rod 29, thereby forcing the stopper 14 fromhole 28 in cylinder 25.

For the purpose of supplying a support against the handle 35 falling tothe floor when manual grasp is released from the handle, the rectangularends 45 of support 46, shown in Fig. 12, may be inserted in holes 47 inends 19 of casing 2, whereby the arms 36, of the handle 35, is adaptedtocon: tact the support and limit the movement of the handle in thedirection toward the support. The arrangement is represented by dottedlines in Fig. 1. However, for use with the design of handle 35 as shown,the

push-rod should be centrally disposed of the top 24 of the casing, orthe handlemay be designed for utilization in consideration of thepush-rod, whereby curved member 44 is adapted to engage the top of thepush-rod. For the purpose of releasably maintaining the retainer 4 inopen bottom 16 of the casing, the screws 48 are received in the loweredge of the casing, and their inner ends are threaded in ends 49 ottheretainer, whereby when the bristles become worn, the screws ma beremoved anda new brush may be quickly andconveniently secured inposition for use with the casing 1.

In hole 50 in the top of the casing is threaded plug 51, whereby thecasing may be refilled with liquid soap by unscrewing the plug. 1 a

The push-rod 29 may be positioned at the side of easing 1, or in otherpositions not shown in the drawings, but when handle 35 is incorporatedwith the invention it is importantfor the push-rod to bepositionedbeneath curved members 44.

In Fig. 10, I show a modified-form of the invention adapted to containpaste or cream soap and tubes 13' are secured in holes 15 in retainer 4,slidably received in compartment 52 of the casing. Extending outwardlyfrom ends 50 of the retainer are springs 53 adapted to engage teeth 54in the inner surface of end 19 of the casing, whereby downward pressureon the top 24 of the caring is adapted to force the retainer upwardlywithin the compartment of the casing,- and the soap paste or cream isforced instances, it may be advantageous to sub stitute felt, materialor the like for the bristles.

It is apparent that I have invented a highly desirable device for thepurposes intended and which may be utilized for various kinds ofbrushes, such as tooth-brushes.

or other kinds of brushes, where 'it is desirable to apply a liquid orpaste in contact with the bristles thereof.

til

brushes with cakes of soap, because as is well known many seriousaccidents have occurred as a result of persons accidentally steppingupon a cake of soap which is very slippery and may easily cause theperson to fall. I

l/Vhile I have chosen to illustrate the forms and constructions of theinvention by the herein drawings and explanations of the same, it isunderstood that the invention resides in the combination, arrangement01' the parts and in the details of the construction, as hereinafterclaimed. It is further understood that changes in the precise embodimentof the invention as disclosed herein, can be made within the scope ofwhat is claimed Without departing from the spirit of the in vention, asother eXpedients may readily suggest themselves to the art.
